This is a black leather sling/messenger bag with a long adjustable shoulder strap.
A few details :
The material appears to be pebbled leather, which is durable and has a textured look.
The brand name "ESQUIRE" is embossed on the front flap. Esquire is known for making men’s accessories like wallets, belts, and bags.
The strap is made of nylon webbing, which makes it lightweight and comfortable to carry.
The corners at the bottom are reinforced with extra leather patches, likely to protect against wear and tear.
The bag seems spacious and slim, suitable for carrying essentials like documents, a tablet, or everyday items.
It looks like a practical everyday bag for office, travel, or casual use, especially if you prefer something professional-looking but not bulky.
